Determination of weed seeds contaminating wheat grainsin Southeastern Anatolia region of Turkey


Abstract: This study was conducted to determine species of weed seeds and their average ratioswithin wheat grains. The samples were taken randomly and mixed in a sample bag. 154, 50, 100,214, 43, 46 and 110 wheat samples were collected in Adıyaman, Batman, Diyarbakır, Gaziantep,Kilis, Siirt and Şanlıurfa provinces respectively between 2001 and 2005. The weight and numberof weed seeds in wheat samples were determined. The number of weed seeds in 1kg of thesample taken from Adıyaman was 801.89 (=16.72g), while it was 995.72 (=14.79g) for Batman,538.49 (=16.96g) for Diyarbakır, 680.54 (=15.32g) for Gaziantep, 1025.36 (=16.41g) for Kilis,492.86 (=12.84g) for Siirt and 1337.16 (=24.14g) for Şanlıurfa.
